Hi there. My door is all one piece of glass from top to bottom so I don't have different panes within it. Another idea I came up with is to make the entry/exit through my air conditioning hole. I am planning to get rid of it anyway. The house came with it and it's old, but I think if I remove it I'll have a good size space to put in the cat door. What do you think of this idea?
I may not get on a computer again today, but I'll look for your message over the weekend. Thank you!
